` To all 'wh'omit may concern.: u

I Be it known that I, CHARLES H. HELMs, of Poughkeepsie, county ofDutchess, and State of New York, have invented certain new anduseiulImprovements in Machines for Trimming-Heels of Boots and Shoes;V

andado hereby declare thefollowing to bel a full, clear, and exactdescriptionthereof;i reference being had to the accompanyingdrawinganfwhich-fi Figure Cshows thecutter-Wheel constructed :unterd-ying to my invention.`

Fig.`G. y

l1`igures A-and I3` are elevations of arrangemeutof cutter-wheel andsand and resp-wheels upon same Wheel by which I'can trim both sidesofthe heelto a boote or shoe, without the boot Vpassing to differentApersons, or employing-.adi'erent wheel; that isg-I wis-h to trim bothsides," of the heel upon one wheel.v This I can'do-uponwheel inlrig. O,or its equivalent, h'; -And The nature of my intention consists in -adouble cutter-wheel, having a double-faced 'shoulder atfthe centre ofthe surface, so"that the heel may be half trimmed upon one side of :thewheel, the bottoni of the heel' bearing against one face of shoulder,and the other side of the heel` trimmed on the opposite.

In the drawingsy v v h,` h" representthercutterj-wheel, provided withadjustable cutters c c and double-faced shoulder g.

The advantage of" this construction enables me 4to triinone sideof thelicei, from front tocentre of back,

Figure D is sectional viewof saine, on line a bof upon one side ofcutter h, and` theother side turned and trimmed by the sameworkman, theshoulder g .keeping the heel to the-propel` position.

` The wheel h', shown upon the shaft S, is an equivalent construction,but does not do the work so wellV no1' so easily as h". A i

Thearrangement of etter-wheels,.sand and raspwheels upoirlthe sameshaft, issimply a convenient arrangement, but does not partake of thenature of an invention, .nor do I claim any. Iain aware that burr-wheelswith guide have J.been made and patented, but they are old, and I claimnothing of the kind; butI I am not aware thatra cutter-wheel, as shownin Fig; O, Was'ever usedor constructed; audit meets a want inshoe-manufactories. The wheel h is Whole,-an`d the shoulder isfast withrIfhe arrangement of theadjustable cutters c is not new.

as cutter-wheel h, to great advantage..

The double cutter-wheel h, having double-faced shoulder g, 4and providedwith adjustablel cutters, substantially as, set forth.v 4

y In testimony whereof, I have hereunto set my hand, this 23dV dayofOctober, 18.69, in presence-of two subscrbing witnesses.
